1.

figure shows a neutral metallic sphere with a point charge +Q placed near its surface. Electrostatic equilibrium conditions exist on metallic sphere. Mark the correct statement :

Answer»

Net flux throughGaussian surface due to charge Q is zero
Net flux through Gaussian surface due to CHARGES appearing on the outer surface of metallic sphere MUST be zero
if point CHAGE Q is displaced a little towards metallic sphere, magnitude of net flux through right hemisperical closed Gaussian surface increases.
If point charge Q is displaced towards metallic sphere, charge distribution on outer surface of sphere will change

Answer :a,b,C,d
